1. A user visits a page that displays a list of products, but the data is still loading from the server. Which UI element should appear to indicate this loading process?

   1. A modal asking the user to wait
   2. A skeleton or spinner showing placeholder rows
   3. An empty state with a 'No products found' message
   4. An error message suggesting the user try again later

2. What is the primary purpose of an 'empty state' in a list interface?

   1. To hide the list until the user explicitly requests it
   2. To prompt the user to create the first item rather than showing a blank screen
   3. To show a warning when the user has no internet connection
   4. To automatically populate sample data for demonstration

3. What does 'optimistic update' mean in UI design?

   1. Using AI to predict what the user will click next
   2. Showing the success state instantly while the server processes in the background, then rolling back if it fails
   3. Only updating the UI after receiving server confirmation
   4. Updating the server first, then the UI

4. What is the function of an 'auth gate' in an application?

   1. To collect user feedback after each action
   2. To remember user preferences across sessions
   3. To automatically log users out after inactivity
   4. To block access to certain pages until the user signs in

5. A user clicks delete on an item. What does the lesson recommend to prevent breaking user trust?

   1. Delete the item immediately without notification
   2. Show a confirmation dialog or offer an undo toast
   3. Require the user to type the item name before deletion
   4. Ask the AI to decide whether to delete it

6. Why is it important to specify loading, empty, and error states when prompting an AI to build a list?

   1. Because the AI cannot render any UI without these states
   2. Because lists cannot function without them
   3. Because these states are required by law
   4. Because the AI defaults to only the happy path where everything works

7. What is the 'detail' pattern used for in application design?

   1. Filtering items based on user criteria
   2. Creating a new item from scratch
   3. Showing one expanded item with options to edit or delete it
   4. Displaying a summary of multiple items at once

8. Which pattern would you use when you need quick actions without navigating away from the current page?

   1. Modal pattern
   2. Form pattern
   3. Search and filter pattern
   4. Auth gate pattern

9. What is the relationship between naming design patterns and working with AI coding tools?

   1. Naming patterns is unnecessary because AI already knows them
   2. Naming patterns only works for simple apps, not complex ones
   3. Naming patterns in prompts helps the AI build correctly without needing multiple corrections
   4. Naming patterns allows the AI to write faster code

10. What should appear when a fetch request fails in a list interface?

    1. A loading spinner that never stops
    2. An error message with a retry button
    3. The previous data if available, silently
    4. A friendly message prompting the user to create the first item

11. What does the 'search and filter' pattern enable users to do?

    1. Narrow down a list based on criteria or search terms
    2. Change the visual theme of the interface
    3. Add new items to a list
    4. Export data to a spreadsheet

12. The lesson compares three states for a list: Loading, Empty, and Error. What does the 'Loading' state use as its visual representation?

    1. A friendly call-to-action button
    2. A success message
    3. A modal overlay
    4. A skeleton or spinner

13. What is the main risk of building an app with only the 'happy path' in mind?

    1. The app will look perfect but break when real users interact with edge cases
    2. The app will use too much memory
    3. The app will be too colorful
    4. The app will run too fast

14. Which of the following is NOT one of the seven patterns covered in the lesson?

    1. Animation
    2. Detail
    3. Search and filter
    4. List

15. The lesson mentions shadcn/ui gallery, Vercel's design system, and Refactoring UI as resources. What is the common purpose of these resources?

    1. They are AI models that write code for you
    2. They are hosting platforms for deploying apps
    3. They are programming languages for building UIs
    4. They provide copy-paste components and visual rules for implementing patterns
